CFG Pile Consolidation for Backfill Rolling Compacted Foundation
Abstract:According to the conditions of backfill rolling compacted foundation, CFG pile composite foundation with high replacement ratio was selected. With the rational structure form of composite foundation, the mechanical characteristics were improved for obtaining full bearing capacity of the pile and the soil between piles to increase the capacity of the foundation and reduce the foundation settlement.
